Schritte zur Lösung

\int_{4.6}^{7} 12 x^{2} - 6 x + \frac{4}{x} d x

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{4.6}^{7} 12 x^{2} d x - \int_{4.6}^{7} 6 x d x + \int_{4.6}^{7} \frac{4}{x} d x

\int_{4.6}^{7} 12 x^{2} d x = 982.65599 \dots

\int_{4.6}^{7} 6 x d x = 83.52

\int_{4.6}^{7} \frac{4}{x} d x = 1.67941 \dots

= 982.65599 \dots - 83.52 + 1.67941 \dots

\int_{0}^{l n (3)} \frac{x}{x ^{2} - 3 x} d x

\int_{- 1}^{1} \frac{12}{1 + x ^{2}} d x

\int_{0}^{π} \frac{7}{3} sin (x) d x

\int_{0}^{2} x (1 - \frac{1}{2} x) d x
